2 Claims. (Cl. 15160) This invention relates to new and useful improvements in paint brushes for household, industrial, and other painting.

More particularly, the present invention proposes the construction of an improved paint brush which Will save ytime in painting objects having round or sharp edge corners..

Another object of the present invention proposes forming the paint brush with converging bristles and with a brush tip opening to receive the angular or arcuate corner surfaces of various objects for simultaneously and uniformly applying paint to such surfaces.

Still further, the present invention proposes constructing the brush opening so that both sides of square or other sharp corners on objects such as furniture, fences, Windows, woodwork, pipes, tire-escapes, posts and the like can be painted with one stroke of the brush.

As a further object of the present invention proposes providing two bristle holding members and arranging these bristle holding members of the brush so that they may be moved with relation to one another and secured various -distances apart Ito vary the size and shape of the brush tip opening in the converging bristles.

The present invention further proposes arranging the brush tip opening so that it will receive and paint at least one sixt-h more of the circumference of round objects than can now be painted at one time with conventional brushes.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

ln `the accompanying drawings forming a material part of this disclosure:

Fig. l is a top plan View of a modification of the improved paint brush of the present invention illustrating how it can paint objects of round and square cross section and protruding corners.

Fig. 2 is a similar View to Fig. l but showing another modification of the invention.

Fig. 3 is another view similar to Fig. 1 but showing a still further modified form of the invention.

Fig. 4 is a fragmentary enlarged View similar to Fig. 1, but illustrating a preferred form of the present invention.

Fig. 5 is a section taken on line 5 5 of Fig. 4.

The paint brush, in accordance with the rst form illustrated in Fig. 1, has a handle of wood, plastic or other such material.

Converging bristles 16 and 17 are secured to the upper end 18 of the handle 15 at their diverging ends being fastened by cement or fusion as by dielectric heating. The usual shield or band 19 encircles the upper end of the brush handle 15 adjacent the point where the bristles are secured. The band or shield 19 is secured to the handle 15 by rivets 20.

A notched shaped opening 21 is provided in the bristles 16 and 17 at the center of the brush. This may be formed ICC object 23 'which is square in cross section or the object y24 having an angular protruding corner. While the bristles 16 and -17 may be disposed at various converging angles, -a particularly desirable arrangement is to dispose them "diagonally at forty-tive degree angles on the handle 15. The :bristles -16 and 17 may be of thermoplastic, such as nylon, 'or natural animal bristles.

ln Fig. f2 the bristles 16 and 17 form a round opening 321'4a`t the tip of the brush adapted to receive rounded surfaces such-as the object 22. In other respects this form of fthe-invention issiinilar to the previous form and similar parts may be recognized by the corresponding reference vnumerals with'a prime added.

in Fig. 3 the ytiprof the bristles 16a an-d 17a are formed VAin a :pointed :apex 214 for painting grooved surfaces. In 'other respects this form of the invention is similar to the previous forms and similar parts may be recognized by corresponding reference numerals with the exponent a added.

The preferred form of the present invention illustrated in Figs. 4 and 5 is characterized by the provision of a handle 25 having flat sides 26 and 27 and end edges 28 and 29 and a substantially flat upper end edge 36.

Two bristle holding members 31 and 32 have secured therein and diagonally extending therefrom bristles 33 and 34 respectively. The secured ends of the bristles may be held in the members 31 and 32 by cement or may be set in rubber 35. The bristles 33 and 34 may be natural animal bristles or thermoplastic bristles such as nylon, in which case a thermoplastic may be substituted for rubber 35 and the thermoplastic bristles fused thereto.

Recesses 36 and 37 are provided in the sides 26 and 27 respectively of the handle 25 and two retainer bands 38 and 39 are secured therein to the handle by rivets 40. The Ibands 38 and 39 extend beyond the upper end edge 30 of the handle. Bands 3S and 39 have inwardly disposed anges 41 and 42 respectively with leaf springs 43 and 44 dependent from the respective ledges. The leaf springs 43 and 44 are secured by screws 45 and project downwardly sufficiently to Contact and press against the upper side edges of the bristle holding members 31 and 32 to bias the bottoms of these members against the upper end edge 30 of the handle. In this manner the bristle holding members 31 and 32 are slidably held to the upper end of the handle.

Mating spaced projections 46 and recesses 47 are provided in the bottoms of the bristle holding members 31 and 32 and in the upper end edge 30 of the handle to hold the members 31 and 32 at various fixed distances apart. The bristles 33 and 34 are of varying lengths to provide openings of different sizes and shapes at the tip of the brush, such as opening 43 shown, depending on the proximity of the bristle holding members 31 and 32.

When the bristle holding members 31 and 32 are insei-ted between the bands 38 and 39 from the end edges 28 and 29 of the handle, the bristles 33 and 34 will converge at their free ends. The closer together the members 31 and 32 are slid however, the smaller the opening 48 in the brush tip becomes and conversely the further apart the members 31 and 32 are moved the wider opening 48 becomes. The projections 46 on the handle and the recesses 47 in the members 31 and 32 act as detent means, the springs 43 and 44 providing the biasing force.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to` the precise constructions herein disclosed and the right is reserved to all changes and moditications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent l. A paint brush for painting objects with angular and arcuate surfaces comprising a handle having an upper end, two bristle holding members each with a plurality of bristles secured therein and diagonally exten-ding therefrom, and means removably and adjustably to secure each of said members to said end of the handle with the free ends of the bristles extending from said members converging, said means being two elongated retainer bands secured to the respective sides of the handle and extending beyond one end thereof, said bands each having an inwardly disposed flange with a spring dependent therefrom and engaging said bristle holding members, and mating spaced projections and recesses in the bottoms of the bristle holding members and the end of the brush to which the bands are secured for the springs to hold the holding members so engaged.
